【摘要】 多子波地震道分解是一种新的地震道分解技术,它是以分解算法将地震道分解成不同形状,不同频率的子波。利用多子波地震道分解等技术,对东海平湖油气田花港组油藏地震数据体进行多子波地震道分解与重构、频谱衰减和数据体波形分解等应用研究,找出了与钻井资料吻合,并含有地质意义的属性,勾画出该地区主要油藏的含油气范围和有利目标,取得了较好的应用效果。更多还原

【Abstract】 Multi-wavelet seismic trace decomposition and reconstruction is a new kind of seismic trace decomposition technology,which separates the seismic traces into a series of wavelets with different shape and different frequency using the decomposition algorithm.By applying the multi-wavelet seismic trace decomposition and reconstruction,study on frequency spectrum attenuation and volume based waveform decomposition processing on the seismic data which represents the oil reservoirs in Huagang formation was carried on,those attributes which have the distinct geological meaning and good relativities with wells were found out,and hydrocarbon bearing area in different reservoir were clearly portrayed.更多还原
